To rtl] lull/m, llt ln/(ty con/cern.-

Be it known that I, JOHN J. LE SAUVAGE, a citizen of the United States, and a resident oi' the city of New York, borough of Brooklyn, in the county or' Kings and State of New York, have invented a new and Improved Thimble, of which the following is a tull, clear, and exact description.

My invention relates to the thimbles employed in chimney-openings to adapt them to receive the smoke-pipes of heating apparatus. lts principal objects are to provide means for securing a capability for a movement of the smoke-pipe laterally ofthe thimble while still furnishing a proper closure between the pipe and thimble under normal conditions.

Reference is to be had to the accompanying drawings, forming a part of this specica tion, in which similar reference characters y indicate similar parts in the several views.

Figure 1 is a perspective view of a range connected to a chimney through one embodiment of my invention. Fig. 2 is a vertical section through the opening in the chimney-breast, showing the thimble in place and an elbow in cooperation therewith, parts being broken away. Fig. 3 is an enlarged transverse section on the line 3 3 of Fig. 2, and Fig. 4is ahorizontal section on the line 4 4 of Fig. 3.

The numeral 10 designates a portion of a chimney-breast in which is an opening 11. Situated in proximity to the chimney, below the opening, is a heater or range 12, the waterfront of which is connected by piping 13 with the usual boiler 14, thus rendering it impossible to move the range from the chimney without disconnecting the water-front. At the rear of the range is the usual smoke-opening surrounded by an upwardly-extending flange 15, which receives a drum 16 of an elbow, which has an arm 17 projecting into the chimney-opening.

My improved thimble, which adapts the opening to the elbow, comprises a plate-18, extending from and just outside of the chimney-opening and having in alinement with said opening an opening 19, which is elongated vertically of the chimney and at least its lower portion 20 is of semicircular contour. Projecting from the pipe-opening into the chimney-opening is a tubular ilange 21, which surrounds the opening 19 and is of the same form. The brickwork of the chimney is built up to this flange in the usual manner. At each side oi' the plate 18 and lying substantially parallel to the axis of the opening 19 is a way 22, conveniently formed by bending over the edge of the plate so that it lies at the opposite side from the ilange 21. In these ways a slide 23 is mounted to move across the thimble-opening and having at its inner end a semicircular recess 24, which may cooperate with the portion 20 of the thimble to furnish a complete circular opening. At the outer or upper end of the slide is a iiange 25, serving as a finger-piece.

With the ordinary cylindrical thimbles a range once set in place and its water-iront connected its elbow cannot be removed to give access to the chimney without either tearing away the breast or disconnecting the water-front. Either of these expedients is ofcourse troublesome. With my improved thimble, however, upon raising the slide the elbow may be drawn upwardly, the elongation of the opening and `flange giving a space in which the elbow-arm may move until the drum clears the range-flange. Then the elbow may be readily withdrawn. At other times the bottom of the thimble-opening and the recess in the slide conform closely to the elbow-arm, furnishing a tight closure.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A thimble consisting oi' a plate having its longitudinal edges bent forwardly and inwardly to form longitudinal guideways at opposite sides of the plate, and provided with a vertically-elongated opening the lower portion of which is semicircular and. with a flange projecting from its rear face and corresponding in shape to that of the opening, and a slide iitting in the guideways and having a semicircular recess in its lower edge coperating with the lower portion of the opening of the plate to form a circular opening, said slide being provided at its upper end with a handle for operating it.`

2. The combination with a chimney provided. with an opening, of a heater situated adjacent to the chimney and having a smokeopening surrounded by a flange, a thimble comprising a plate lying outside the chimney and provided with guideways at its opposing edges, a vertical elongated opening, and a ilange surrounding the plate-opening and ex- TOO tending into the chimney-opening and a slide In testimony whereof I have signed my operating in the guideways across the platename to this specification in Jche presence of opening and having a semieircireular recess two subscribing witnesses.
